How is fart formed in human body? The most important thing is: why do people fart so much? A dozen a day? How can we reduce farting?

Because when people eat food, due to the role of normal flora in the digestive tract, they will produce more gas. These gases move downward with the peristalsis of the intestine and are discharged from the anus. When it is discharged, due to the action of anal sphincter, noise sometimes occurs. Therefore, farting is a manifestation of the normal operation of the intestine. On the contrary, if you don't fart, or fart too much and stink, that's an abnormal phenomenon. Fart is the waste gas discharged by the body, mostly carbon dioxide, hydrogen and methane. It used to be generally believed that the smell of fart was released by methane. In fact, methane itself is not smelly. Modern science has proved that the "culprit" of odor is indole, fecal odor, hydrogen sulfide and other malodorous gases. Pay attention to farting and learn a lot from human civilization. Farting is indecent behavior, especially in public. During the first month, due to the intake of high-protein foods such as meat, smelly fart really annoyed many people. In order to avoid embarrassing scenes, some people simply hold back carefully or make the words clear nervously. In this way, "waste gas" may be dissolved in blood and enter the liver and kidney because of holding back fart ... Farting can distinguish diseases. Pay attention to the common name of "intestinal gas" in time, which is a kind of waste gas discharged from the body through the anus. Healthy people fart different times every day, and the frequency is generally 6-20 times/day. Nitrogen, hydrogen sulfide, ammonia and other waste gases produced by bacteria decomposing residual food in the intestine are mainly discharged from the body through farting, which is beneficial to the human body and a magic weapon for human self-regulation. There is a saying in Hunan that "people laugh at fart and have no ambition", which can be regarded as a name for fart. It is medically proved that you can learn about the stomach by farting. Not farting is not necessarily a good thing, farting too much may be a bad thing, and smelly fart may have an accident. Some people are proud of never farting or seldom farting. In fact, people who fart are healthier than those who don't! Mr. Li, who works in a clinic in Lianhua, said that he had not farted and defecated for several days, and his abdomen ached. According to the examination of the clinic doctor, this is a precursor to intestinal obstruction, because Mr. Li ate too much meat in the first month and did not exercise very much, which led to the accumulation of food in the abdomen, the obstruction of gastrointestinal function and the poor detoxification. In addition, in order to save face, many people often endure farting. Especially some modest gentlemen and ladies, in order to lose their dignity, they would rather hold their faces and not let go. In this way, although the tolerated gas does not break into the door and produce odor, it will accumulate in the large intestine, exchange gas with the blood coming to the intestinal mucosa, and flow with the blood. Toxic gas can't be released in the simplest way, so it can only be detoxified in another way, which not only increases the burden on the body, but also may cause chronic poisoning of the body, causing abdominal distension, bowel sounds, listlessness, indigestion, dizziness, and even peritonitis, intestinal obstruction and other diseases. Don't be careless when farting. Tell a joke about farting that I heard before: Once upon a time, there was a man who loved farting and created a lot of embarrassing situations. In the first month, he will go out to pay a New Year call to his relatives and friends. In order to prevent him from making jokes, the family specially invited the best eloquent master in the village to go with him. Whenever there is an "accident", he will go back and forth for him to eliminate embarrassment. Who would have thought that the man farted as soon as he entered someone else's door? Fortunately, the host was witty and immediately said to the host, I wish you all the best. Unexpectedly, soon after the man was seated, he repeatedly farted, which made everyone very embarrassed. Thank you for your rescue. I wish you all the best. The terrible thing is that the master can't stand the man's constant beating. He said angrily to the man, "You screwed up and I lost face." Laugh back, the more farting, the more thoughtful you really are. Fart means that the anal exhaust volume is much higher than usual for many reasons, such as indigestion, gastritis, peptic ulcer and other stomach diseases, liver, gallbladder and pancreatic diseases. Dyspepsia can be divided into functional and organic, the former is related to gastrointestinal peristalsis dysfunction; The latter is related to diseases such as intestinal inflammation and cancer. In addition, excessive farting may also be caused by eating starchy and protein foods such as beans, potatoes and eggs, or by gorging or habitually swallowing too much, swallowing saliva frequently and inhaling more air. I suggest you don't be careless because you fart too much. You'd better go to the hospital for examination, find out the cause of farting, and then prescribe the right medicine. You should be more careful when you fart. People hate it most. Even a modest gentleman may cover his nose when he smells smelly fart. The main components of fart are nitrogen contained in the swallowed air and hydrogen, methane, carbon dioxide and other gases produced by intestinal bacteria. In general, fart is not particularly smelly. If the fart stinks, there may be the following reasons: First, it is the result of indigestion or eating too much meat. Bacteria will produce hydrogen sulfide, indole, fecal odor and other malodorous gases when decomposing meat products. No wonder some people say that the fart of Europeans and Americans who love meat stinks, which still has certain scientific basis. Second, in the late stage of intestinal malignant tumor, due to the erosion of cancer tissue, bacteria are playing tricks, protein is corrupt, and the gas discharged through the anus can also have carrion-like odor. Third, when the digestive tract bleeds, the blood stays in the intestinal cavity; Or intestinal inflammation, the discharged gas is often malodorous. Four, eat garlic, onions and leeks and other foods containing pungent smell. It's not morbid, but don't worry. There is a folk proverb "fart doesn't stink, fart doesn't ring". The data shows that this is related to the type of food consumed. Eating potatoes, radishes and other foods will produce a lot of carbon dioxide when decomposed. In this case, farting often sounds like thunder, but it doesn't stink too much. Eating too much protein, garlic, beans and other foods will decompose malodorous gases. In this case, farting may not make a sound, but it can "kill people without seeing blood." Tens of millions of bacteria live in the large intestine. They help digest and decompose food residues, and at the same time produce a lot of harmful gases, which must be discharged from the body in time. This is what we call "fart" because fart is good for health. There are roughly two reasons for farting often. One is that you often fart because you eat some gas-producing foods, such as sweet potatoes, onions, cabbage, beans and other soy products. In addition, you may suffer from irritable bowel syndrome, which may also cause abdominal pain, bloating and farting in clinic. In diet, it is recommended that you eat more in small quantities and don't overeat. Chew slowly when eating, avoid eating too much air together and avoid eating food that is easy to produce gas. Drinking a cup of yogurt every day helps to change the bacteria in the gastrointestinal tract. Fart is the waste gas discharged by the body, mostly carbon dioxide, hydrogen and methane. It used to be generally believed that the smell of fart was released by methane. In fact, methane itself is not smelly. Modern science has proved that the "culprit" of odor is indole, fecal odor, hydrogen sulfide and other malodorous gases. Because people's sense of smell is particularly sensitive to these gases, in public places, even if someone secretly farts, people can still quickly find and cover their noses and shout smelly! Fart is produced because some foods we eat are not decomposed. The undecomposed parts, including fiber and sugar, become food for Escherichia coli. Escherichia coli is discharged after a full meal, and these gases accumulate in the body, causing air pressure. Too much pressure will be pushed out of the body, forming a fart. The amount of fart is related to people's diet. Some people like to eat onions, ginger, raw garlic, potatoes, sweets, beans and pasta. Because these foods contain substrates that can produce a lot of hydrogen, carbon dioxide, hydrogen sulfide and other gases, the exhaust gas often increases greatly after eating, and fart constantly. The amount of fart is also related to the strength of human digestive function. When indigestion occurs, intestinal bacteria ferment rapidly, which is easy to produce gas and make people fart. A scientist found that a person farts about 14 times a day. Every day, everyone releases about 500 ml of waste gas. Although fart stinks, fart is a normal physiological need and is beneficial to people's health. It is unhealthy for a person not to fart all day. People who don't fart all the year round are most likely to have gastrointestinal problems. Drinking a cup of yogurt every day helps to change the bacteria in the gastrointestinal tract.
